For a given sinusoidal input voltage, the voltage waveform

Home » Analog Circuits » Analog circuits miscellaneous » Question

For a given sinusoidal input voltage, the voltage waveform at point P of the clamper circuit shown in figure given below will be

Correct Option: D

During the cycle of V_in , diode is cut-off and
V_P = V_i A_v = – V_CC = – 12 volts
During -ve cycle of V_in, diode is ON,
Current through R_L, i_L = 0
Then, V_P = V_L + V_D
= i_LR_L + V_D = 0.7 volts
